Description

Technical Field

[0001] This utility model belongs to the field of PVC edge banding production technology, specifically relating to an embossing machine for PVC edge banding production. Background Technology

[0002] PVC edge banding is a thermoplastic roll material made from polyvinyl chloride as the main raw material, with the addition of plasticizers, stabilizers, lubricants, dyes, and other additives. Its surface features wood grain, marble, fabric textures, and other patterns, with a soft gloss that gives it the realistic and three-dimensional feel of wood. It possesses a certain degree of smoothness and decorative appeal, as well as resistance to heat, chemicals, and corrosion. The surface also has a certain degree of hardness. The main function of edge banding is to seal the cross-section of the board, protecting it from damage caused by adverse environmental and usage factors (mainly moisture) and preventing the volatilization of formaldehyde from within the board, while simultaneously achieving a decorative effect.

[0003] For example, CN 219600389 U discloses an embossing machine for producing PVC edge banding strips. Although this embossing machine for producing PVC edge banding strips completes the cutting and surface coating of the edge banding strips with methyl ethyl ketone (MEK) as the edge banding strips pass through the device, with high cutting efficiency and uniform MEK coating, the edge banding strips lack a limited limiting mechanism, which makes it easy for the pattern to deviate during embossing, thereby reducing the embossing effect of the finished product. Therefore, this utility model provides an embossing machine for producing PVC edge banding strips. Utility Model Content

[0004] The purpose of this invention is to provide an embossing machine for the production of PVC edge banding strips, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an embossing machine for producing PVC edge banding strips, comprising a base, with connecting columns fixedly connected to the four corners of the top of the base, a top plate fixedly connected to the top of the connecting columns, a hydraulic rod fixedly connected to the top of the top plate, a connecting frame fixedly connected to the telescopic end of the hydraulic rod, an embossing disc for embossing PVC edge banding strips rotatably connected inside the connecting frame, and two adjusting plates rotatably connected to both sides of the connecting frame.

[0006] In a preferred embodiment, two side frames are fixedly connected to both sides of the connecting frame, and each adjusting plate is rotatably connected to the bottom of the corresponding side frame near the connecting frame.

[0007] In a preferred embodiment, an arc-shaped guide post is fixedly connected to the bottom of the side frame away from the connecting frame, the adjusting plate is slidably connected to the outside of the guide post, and a return spring is sleeved on the outside of the guide post.

[0008] In a preferred embodiment, each of the adjustment plates is rotatably connected to an auxiliary roller at its bottom end, and a drive motor connected to the embossing plate is provided on one side of the connecting frame.

[0009] In a preferred embodiment, two symmetrically arranged guide members are provided on both sides of the top of the base, and each guide member includes a fixing frame fixedly connected to the top of the base.

[0010] In a preferred embodiment, the mounting bracket has a sliding groove inside, a fixed column is fixedly connected inside the sliding groove, a sliding block is slidably connected to the outside of the fixed column, one side of the sliding block is fixedly connected to a connecting plate, and a guide plate is rotatably connected to the center of the top of the connecting plate near the PVC edge banding strip, with the PVC edge banding strip passing through the bottom of the guide plate.

[0011] In a preferred embodiment, a spring is sleeved on the outside of the fixed column, and the top and bottom of the spring are fixedly connected to the top of the sliding block and the bottom of the inner cavity of the slide groove, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This embossing machine for producing PVC edge banding strips uses a linkage structure of adjusting plates and auxiliary rollers. When the embossing plate presses down, the four adjusting plates drive the four auxiliary rollers to expand to both sides and fit the edge of the edge banding strip. This dynamic limiting mechanism can effectively constrain the lateral displacement of the edge banding strip in the embossing area, avoid misalignment or distortion of the pattern due to material offset, thereby significantly improving the embossing accuracy and three-dimensionality of the finished product and meeting the needs of high-precision decoration.

[0014] This embossing machine for PVC edge banding production adopts a combination structure of spring-supported sliding block and guide plate. Through the elastic buffer of the external spring of the fixed column, the guide plate can adaptively adjust its height according to the thickness of the edge banding. Compared with traditional rigid guiding devices, this design can reduce local extrusion caused by material thickness fluctuations or feed speed changes, avoid wrinkles or scratches on the surface of the edge banding, and ensure the continuity of the production process and the stability of the finished product quality.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figures 1-3 This utility model provides an embossing machine for producing PVC edge banding strips, including a base 1, with connecting columns 2 fixedly connected to the four corners of the top of the base 1, a top plate 3 fixedly connected to the top of the connecting columns 2, a hydraulic rod 4 fixedly connected to the top of the top plate 3, a connecting frame 5 fixedly connected to the telescopic end of the hydraulic rod 4, an embossing disc 6 for embossing PVC edge banding strips rotatably connected inside the connecting frame 5, two adjusting plates 11 rotatably connected to both sides of the connecting frame 5, two side frames 8 fixedly connected to both sides of the connecting frame 5, each adjusting plate 11 rotatably connected to the bottom end of the corresponding side frame 8 near the connecting frame 5, an arc-shaped guide column 9 fixedly connected to the bottom of the side frame 8 away from the connecting frame 5, the adjusting plate 11 slidably connected to the outside of the guide column 9, and a return spring 10 sleeved on the outside of the guide column 9, an auxiliary roller 12 rotatably connected to the bottom end of each adjusting plate 11, and a drive motor 7 connected to the embossing disc 6 on one side of the connecting frame 5;

[0022] Hydraulic rod 4 is in the retracted position, connecting frame 5 and embossing plate 6 are in the high position, adjusting plate 11 is in the inward state under the action of return spring 10, the spacing of auxiliary rollers 12 is less than the width of the edge banding strip, the arc design of guide column 9 ensures that adjusting plate 11 forms a lever structure with side frame 8 as the fulcrum, return spring 10 provides initial preload, PVC edge banding strip is conveyed to the embossing station by feeding roller, hydraulic rod 4 is pressed down, driving connecting frame 5 and embossing plate 6 to move vertically, synchronously driving adjusting plate 11 to expand outward along guide column 9 after contacting base 1, adjusting plate 11 is constrained by guide column 9, forming a lever movement with side frame 8 as the fulcrum, auxiliary rollers 12 expand outward and fit the two sides of edge banding strip, return spring 10 is compressed, ensuring that the auxiliary roller 12 forms a dynamic clamp on the edge banding strip (the pressure adapts to the material thickness). The embossing disk 6 contacts the surface of the edge banding strip, and the drive motor 7 starts synchronously, driving the embossing disk 6 to rotate, thus achieving pattern pressing. The auxiliary roller 12 rotates synchronously with the edge banding strip feed direction, converting the lateral shear force into rolling friction to avoid material deviation. The adjusting plate 11 forms an elastic floating system with the guide column 9 and the return spring 10, allowing the edge banding strip to undergo slight deformation due to embossing, while maintaining lateral limit accuracy. The hydraulic rod 4 retracts, the embossing disk 6 and the adjusting plate 11 reset, the return spring 10 pushes the adjusting plate 11 to retract, and the auxiliary roller 12 disengages from the edge banding strip, completing a single embossing cycle.

[0023] The lever structure of the adjusting plate 11 and the arc-shaped constraint of the guide column 9 make the expansion trajectory of the auxiliary roller 12 geometrically match the width change of the edge banding strip. When the width of the edge banding strip fluctuates due to thermal expansion and contraction, the auxiliary roller 12 can automatically adjust the limit range. The elastic buffering effect of the reset spring 10 reduces the pressure fluctuation of the embossing plate 6 on the edge banding strip, avoiding uneven pattern depth due to sudden pressure changes. The dynamic limit mechanism reduces the need for manual intervention.

[0024] In this embodiment, two symmetrically arranged guide members are provided on both sides of the top of the base 1. Each guide member includes a fixed frame 13 fixedly connected to the top of the base 1. A sliding groove is opened inside the fixed frame 13. A fixed column 14 is fixedly connected inside the sliding groove. A sliding block 15 is slidably connected to the outside of the fixed column 14. One side of the sliding block 15 is fixedly connected to the connecting plate 16. A guide plate 17 is rotatably connected to the center of the top of the side of the connecting plate 16 near the PVC edge banding strip. The PVC edge banding strip passes through the bottom of the guide plate 17. A spring is sleeved on the outside of the fixed column 14. The top and bottom of the spring are fixedly connected to the top of the sliding block 15 and the bottom of the inner cavity of the sliding groove, respectively. The PVC edge banding strip is conveyed to the guiding station by the feeding roller and its surface contacts the bottom of the guide plate 17 to form a preliminary guiding constraint.

[0025] When the edge banding strip passes through, the guide plate 17 is driven by the friction of the material surface, and drives the sliding block 15 to slide upward along the fixed column 14 through the connecting plate 16, compressing the spring. The displacement of the sliding block 15 is compensated in real time by the spring compression. During the upward movement of the guide plate 17 with the sliding block 15, it always maintains an elastic contact gap with the surface of the edge banding strip. Through rolling friction (the surface of the guide plate 17 is covered with Shore 50 hardness rubber), the lateral shear force is converted into rolling resistance to avoid material deviation. The four sets of symmetrically arranged guides form a "four-point limit" structure to achieve lateral positioning accuracy control. When the embossing plate 6 presses down on the edge banding strip, the guide spring is further compressed due to the material deformation to avoid excessive extrusion that causes material deformation. During the embossing process, the guide plate 17 continuously provides dynamic limit to ensure the flatness of the material in the embossing area and avoid pattern deformation due to material undulation. After the embossing is completed, the spring releases its stored energy, pushes the sliding block 15 back to the initial position, and the guide plate 17 is removed from the surface of the edge banding strip, completing a single guide cycle.

[0026] The working principle and usage process of this utility model are as follows: First, the PVC edge banding strip is conveyed to the guide station by the feeding roller, and its surface contacts the bottom of the guide plate 17, forming an initial guiding constraint. When the edge banding strip passes through, the guide plate 17 is driven by the friction force of the material surface, and the sliding block 15 is driven to slide upward along the fixed column 14 through the connecting plate 16, compressing the spring. The displacement of the sliding block 15 is compensated in real time by the spring compression. During the upward movement of the guide plate 17 with the sliding block 15, an elastic contact gap is always maintained with the surface of the edge banding strip. Through rolling friction (the surface of the guide plate 17 is covered with Shore 50 hardness rubber), the lateral shear force is converted into rolling resistance to avoid material deviation. The four sets of symmetrically arranged guide components form a "four-point limit" structure to achieve lateral positioning accuracy control. The PVC edge banding strip is conveyed to the embossing station by the feeding roller, and the hydraulic rod 4 is pressed down, driving the connecting frame 5 and the embossing plate 6 to move vertically, synchronously driving the adjusting plate. After contacting the base 1, the adjusting plate 11 expands outward along the guide post 9. The adjusting plate 11 is constrained by the guide post 9 and forms a lever motion with the side frame 8 as the fulcrum. The auxiliary roller 12 expands outward and fits against the two sides of the edge banding strip. The return spring 10 is compressed to ensure that the auxiliary roller 12 forms a dynamic clamping on the edge banding strip (the pressure adapts to the material thickness). The embossing disk 6 contacts the surface of the edge banding strip, and the drive motor 7 starts synchronously, driving the embossing disk 6 to rotate and realize the pattern pressing. The auxiliary roller 12 rotates synchronously with the feeding direction of the edge banding strip, converting the lateral shearing force into rolling friction to avoid material deviation. The adjusting plate 11 forms an elastic floating system with the guide post 9 and the return spring 10, allowing the edge banding strip to undergo slight deformation due to embossing, while maintaining lateral limit accuracy. The hydraulic rod 4 retracts, the embossing disk 6 and the adjusting plate 11 reset, and the return spring 10 pushes the adjusting plate 11 inward. The auxiliary roller 12 disengages from the edge banding strip, completing a single embossing cycle.
